To open the front gate from the closed position
Send txt (Gate On) – Applies +12V to the output of the I/O Board.
Convert +12V to a pulse to activate button 1 or 2 (both buttons are programmed to open or close the gate) on the remote to open or close the front gate.
Send txt (Gate Off) – Turns off +12V output on the I/O Board.

The same process will need to be followed to close the front gate again.
